ANY SPHERICAL FRUIT.

Patented'Nov. 10, 1914.

To all whom it may concern:

Be it known that I, rm'mo, a citizen of the United States, and

in the county of Hillshave invented a new and useful Improvement inFlexible Knives for the Extraction of Essential Oils and Removal ofPeelingsv from any Spherical Fruit, of which the following is aspecification. 1

My invention-relates to the im rovement in extracting the essential oilsan removing the peeling from fruits by using a knife made of severaljointed sections, which can be flexed and ada ted to any shape of fruit,

and attached to t e machines used now for are pivoted together. to makeup a the. fruit. In assuming this shape, I corners to which the coilsprings 8 are con-:1

said purpose.

Referring to the'accompanying drawing, Figure 1 is a view inelevation ofthe face of one of the lmife sections; Fig. 1 is a similar view of-oneed e thereof; Fig. 2 is a view in elevation 0 several connected tions ofthe knife; and Fig. 3 is an elevation of the complete knife, enclrclinga spherical fruit as an orange.

In the drawing, ignates the knife sections, which are substantiallyrectangular, and have serrated cutting edges 2. The corners opposite thecutting ed es are provided with openings 3 and the ot er corners 4 and 5are apertured as at' 6 to receive (pivots 7 whereby overlap- 5 of" theadjacent sections flexible further connected ing corners 4 an knife. Thesections are togetherby spring coils 8 having their ends hooked in thesaid apertures 3.

In operation, the" knife is placed about the fruit with the cuttingedges engaged with the periphery thereof and, asthe sections 1 turn ontheir pivots, the cutting edge of one section moves adjacent that ofthe'others to decrease the ga and to cause the cutting edges to form analinement co-incidentwith the contour of theouter Amsrmn Gramasecreference numeral 1 des-' tions having cutting ing to normally forcethe cutting edges of ps 9 between the sections 1 nected move away fromeach other, placing the springsunder tension, andupon completlon of thecutting operation, these springs return the sections to their normalrelation in which their cutting edges form I a, right line.

In operation, ably is, rotated by hand or mechanical means, stead thefruit may remain stationary and the knife bodily rotated whollyorpartially about the fruit. The movement of the knife or fruit,however, is relative, and the means for producing the movement isimmaterial".

It is evident, therefore, v that the knife being springy, can be adaptedto most any size or shape of fruit and by the pressure and movement ofthe knife overthe surface of the fruit, theteeth of the knife will cutthe cells containing'the essential oils and located principally in theyellow coat of the rind, and set free the oil they contain, and laterremove the peeling entirely ifso dewithin the inclosing knife,

sired.

What I- claim is: p 1. A flexible knife comprisin edges, an meanstendthe sections into alinement with each other. 2. A flexible knife,comprising ointed sections havin cutting edges on one side of thejoints, an coil springs connecting the 'portionson opp osite sides ofthe joints and normally drawing said portions ofjadjaoent sectionstogether; 7

the fruit may, and preferthough mjointed sec- 1 3. A' flexible memberadapted to be'wrap ped about an object, and means for straightening outthe flexible member when released from about the object, said flexiblemember having aJcutting-edge for acting upon the object;
